I am 38 years old and have been taking Loestrin since August 07. Since beginning this pill my periods have NEVER come during the 4 day "off" time period of the pills. My period has remained inconsistent. This past January I started bleeding twice a month. My migraines have increased in intercity and frequency, the bleeding and cramping is horrible. I am losing large blood clots and experiencing dizzy spells. I have made a doctors appt for Monday and have stopped taking the pills after this last period. I was put on this pill because of a history of migraines, but they have just gotten worse and always occurr right before my period starts.
